This timely meeting (appropriately held in Toruń, the “city ofCopernicus”) provided an excellent venue for researchers to reviewthe theoretical and observational progress in the intervening years,share recent results, and make preparations for progress inthe quests to learn whether our Solar System is typical and tounderstand how our own Solar System relates to the rest of theUniverse. It had been nearly six years since the last majorscientific meeting focusing soley on multiple planet systems andplanets in multiple star systems in Saas Fee, Switzerland duringSeptember of 2002 (Udry et al. 2006). Here I review some of theobservational and theoretical progress in understanding multi-bodysystems reported in Toruń.
